The person behind the tools.
Hey, I'm Chris Gage — I live in the Scottish Borders with my daughter Eilidh, and I've spent more time than I care to admit staring at spreadsheets trying to figure out the best way to manage money.
I work in programme leadership by day, which means I'm pretty comfortable with data, planning, and thinking a few steps ahead. I've applied all of that to my own finances — debt, investing, property, pensions — and built these tools along the way because the ones I found online either didn't cover Scotland properly, looked terrible, or wanted me to sign up for something.
These tools are free and always will be. I make a small commission if you click through to a product via this site, but I only link to things I'd genuinely recommend.
Most personal finance tools online are built for England. They don't account for Scottish income tax bands, which are genuinely different and matter a lot if you earn between £26k and £75k. I kept having to mentally adjust every calculator I used.
I also wanted tools that felt like they were made by a real person — not a faceless fintech brand trying to upsell me something. So I built them myself, and figured I might as well put them online in case they're useful to anyone else in a similar situation.
If something's wrong, unclear, or missing — drop me a message via chrisgage.org. I actually update these.
Things I've learned the hard way about money, investing, and making it work in Scotland.
Avalanche vs Snowball: which debt strategy actually works?
The maths says avalanche every time. But the psychology says snowball for a lot of people. Here's how to pick the right one for you.
The Scottish income tax bands explained (and why they matter more than you think)
If you earn between £26k and £75k and live in Scotland, you're paying more income tax than your English colleagues. Here's what to do about it.
Your emergency fund: how much is actually enough?
The "3-6 months expenses" rule is a starting point, not a target. Here's how to work out the right number for your situation.
Salary sacrifice: the tax saving most people ignore
Cycle to work, EV schemes, extra pension — if your employer offers these and you're not using them, you're leaving money on the table.
ISA vs SIPP: which one should you prioritise?
Both shelter your money from tax. But they work very differently. Here's how I think about the split and what I actually do with my own money.
Saving for a house deposit in Scotland: what actually helps
LBTT is different from stamp duty. The LISA has quirks. And the market in the Central Belt vs the Borders is very different. Here's the honest picture.

Two ways to enter your past service
You can use this calculator in two ways depending on whether you have your annual benefit statement to hand.
Option 1 — I have my benefit statement: Leave "Years of Existing CS Service" at 0 and enter the annual pension figure from your statement into "Existing Pension Accrued". This is the most accurate approach. You can find your statement by logging into MyCSP at mypension.civilservice.gov.uk.
Option 2 — I don't have my statement: Leave "Existing Pension Accrued" at 0 and enter your years of service. The calculator will estimate your past pension based on your current salary and scheme rules. This is a reasonable approximation but will be less precise than using your actual statement figure.
Which scheme am I in?
If you joined the Civil Service after April 2015, you are almost certainly in Alpha. If you joined between 2007 and 2015, you are likely in Nuvos. Classic, Classic Plus and Premium are closed to new entrants and cover those who joined before 2007. If you are unsure, check your payslip or contact your HR team.
Understanding the results
The calculator splits your projected pension into past service (what you have already built up) and future service (what you will accrue between now and retirement). The total is your estimated annual pension income in today's terms. For Alpha and Nuvos this is a career average — each year's slice of salary is locked in and revalued by CPI. For Classic and Premium your whole pension is based on your final salary, so past service also benefits from future pay rises.
The commutation option lets you trade part of your annual pension for a one-off tax-free lump sum at retirement (£12 lump sum per £1 of annual pension given up). Whether this makes sense depends on your circumstances and life expectancy.
Normal Pension Age
Alpha: 67 (or State Pension Age if later). Nuvos / Classic / Premium: 65 or 60 respectively. Taking your pension before Normal Pension Age results in a permanent reduction of approximately 5% per year early. The scenarios table shows the impact of retiring 3 years before or after your planned date.
See how your spending compares to the 50/30/20 and 60/20/20 rules — and where to adjust.

Left or planning to leave the Civil Service before retirement? See what your preserved pension will be worth when you eventually draw it.
Work out the tax owed on profits from selling shares, crypto, second properties, or other investments.
Use your annual allowance. The first £3,000 of gains each tax year is tax-free. If you have a large gain, splitting the sale across two tax years can use two allowances.
Spousal transfer. Assets transferred between spouses or civil partners are tax-free, allowing both partners to use their £3,000 allowance.
Bed & ISA. Sell shares held outside an ISA, then immediately re-buy them inside an ISA. Future gains are tax-free.
Offset losses. Capital losses can be offset against gains in the same year, or carried forward indefinitely if registered with HMRC.
Pension contributions. Reducing your total income (via salary sacrifice or extra pension contributions) can keep more of your gain in the basic rate band, taxed at the lower rate.
Reduce future CGT
Investing inside an ISA or SIPP shelters all future gains from CGT.
See how much interest you'll save and how many years you'll knock off your mortgage by overpaying.
Make sure you have the best deal
Before overpaying, check that your interest rate is competitive. A small rate reduction can be worth as much as moderate overpayments.
How each calculator works, the assumptions used, and the official sources behind the numbers.
All calculators are designed to give realistic estimates based on UK and Scottish tax rules and standard financial assumptions. Tax thresholds and rates are sourced from gov.uk and revenue.scot. Pension scheme data comes from the Civil Service Pensions website at civilservicepensionscheme.org.uk.
All projections assume constant rates and growth unless otherwise stated. Real-world outcomes will vary because tax bands change annually, investment returns are not constant, and personal circumstances evolve. Use these tools to inform your thinking, not to replace professional advice.
Scottish income tax bands 2025/26: Starter 19% (£12,571–£14,876), Basic 20% (£14,877–£26,561), Intermediate 21% (£26,562–£43,662), Higher 42% (£43,663–£75,000), Advanced 45% (£75,001–£125,140), Top 48% (£125,141+).
UK income tax bands 2025/26 (England, Wales, NI): Basic 20% (£12,571–£50,270), Higher 40% (£50,271–£125,140), Additional 45% (£125,141+).
Personal Allowance: £12,570 standard, tapered by £1 for every £2 of income over £100,000, fully removed at £125,140. Custom tax codes (including Scottish S-prefix) are supported.
National Insurance 2025/26: Class 1 (employees) — 8% on £12,571–£50,270, 2% above. Class 4 (self-employed) — 6% on £12,571–£50,270, 2% above. Class 2 has been abolished from April 2024.
CGT is set by the UK government and applies across all four nations equally. The annual tax-free allowance for 2025/26 is £3,000.
Rates from 30 October 2024: 18% (basic rate) and 24% (higher rate) on all asset types including shares, crypto, and residential property. The calculator stacks your gain on top of taxable income to determine which rate applies.
Scotland (LBTT): Nil up to £145,000 (£175,000 first-time buyers), then 2%/5%/10%/12% in tiered bands. Additional Dwelling Supplement: 8% on second properties.
England & Northern Ireland (SDLT): Nil up to £125,000 (£300,000 first-time buyers), then 2%/5%/10%/12% in tiered bands. Higher rates surcharge: 5%.
Wales (LTT): Nil up to £225,000, then 6%/7.5%/10%/12% in tiered bands. No first-time buyer relief in Wales. Higher rates surcharge: 5%.
Standard amortisation formula: M = P × r(1+r)^n / ((1+r)^n - 1) where M is monthly payment, P is principal, r is monthly rate, n is number of months.
Affordability check uses 4.5x annual gross salary as a guideline. Real lender assessments vary and consider debts, dependants, expenses and credit history. The overpayment calculator simulates monthly amortisation with extra payments deducted from balance after interest accrues.
Alpha: Career average, 1/43.1 accrual, NPA 67. Nuvos: Career average, 1/43, NPA 65. Classic: Final salary, 1/80 plus 3x lump sum, NPA 60. Classic Plus: Hybrid pre/post 2002. Premium: Final salary, 1/60, NPA 60.
Early retirement reduction is approximately 5% per year before NPA (4.5% for Nuvos). Commutation at £12 lump sum per £1 of annual pension given up.
Deferred pension calculator applies CPI revaluation between leaving date and draw date. Real-world revaluation varies annually and is set by the September CPI figure each year.
Compound growth uses monthly compounding: balance grows by (1 + annual_rate/12) each month after monthly contribution is added. Dividend reinvestment assumes dividends compound at the same rate as growth.
Sustainable retirement withdrawal rate set at 3.5% (slightly below the traditional 4% rule to account for sequence-of-returns risk and longer life expectancy). Real terms toggle adjusts projections by an assumed CPI inflation rate so figures are shown in today's purchasing power.
50/30/20: Elizabeth Warren's classic rule. Suits middle-to-higher incomes with manageable housing costs. 60/20/20: More realistic for high-cost areas where housing alone takes 40%+ of income. 70/20/10: Reflects tighter budgets where saving is constrained but still essential.
These calculators do not currently model: marriage allowance transfer, savings interest tax, dividend tax, the 60% effective marginal rate band between £100k and £125,140, Business Asset Disposal Relief, Inheritance Tax, sequence-of-returns risk in retirement, or Monte Carlo investment simulation.
For complex situations involving these elements, please consult a qualified financial adviser, accountant, or tax specialist.
Tax bands and thresholds are reviewed and updated each April for the new tax year. Major changes to schemes (e.g. Civil Service Pension reforms) are reviewed when announced. Last comprehensive update: April 2026 for the 2026/27 tax year (where applicable).
